What Is My IP Address and What Can Someone Do With It?

Every device online has an IP address – your internet’s return address. Here’s what it reveals and when you’d need to know it.

See yours

Open What Is My IP to see your public IP address, whether it's IPv4 or IPv6, your approximate country, and your browser and screen details.

What it reveals

Roughly where you are – usually the city or region of your internet provider, not your street. It doesn't reveal your name or exact address; only your provider can link it to an account, normally with legal authorisation.

Public vs private

Your public IP is your router's address on the internet. Devices at home use private addresses like 192.168.x.x that aren't visible online.

When you need it

IT support or a service asks to allow-list your IP, you're setting up remote access, or you want to check that a VPN is working (your IP should change when it's on).

Frequently asked questions

Why does my IP keep changing?

Most home and mobile connections get a new IP from the provider periodically.

Can I hide my IP?

A VPN or privacy relay hides it from websites.

Is IPv6 different?

It's a newer, longer address format; many connections have both.
